Try this In[1]:= Series[1/(1+x), {x,0,3}] 2 3 4 Out[1]= 1 - x + x - x + O[x] In[2]:= Normal[%] 2 3 Out[2]= 1 - x + x - x Cheers, Vittorio -----Original Message----- From: highorder [mailto:highorder at Noreply.com] To: mathgroup at smc.vnet.net Subject: [mg52825] [mg52798] Remove the higher order terms in series expansion I guess this should be simple and hiding somewhere in the manual. Is there a quick way to remove the high order terms after using Series[f,{x,x0,n}] command? The problem comes from the output is actually given by: expansion term + O(x^3); the O(x^3) should be removed. I will keep trying but wondering if anyone has a quick answer. Thanks.
